It's defined for both devices that include this dtsi.. perhaps you
could remove it from there

Konrad

I don't have a judyp to test with and prefer to limit scope.

This is a mechanical change

Sorry, I tried to have a look at what you meant but didn't quite understand. In this patch I changed the dtsi that is included by both already. I don't see any other reserved-mem nodes in judyp. Do you mean I should remove the framebuffer from judyp? I don't think that's wise since a panel driver isn't added as far as I know.

I think this warning likely comes from sdm845-mainline repo, as it has extra patches, which trying to abstract framebuffer into sdm845.dtsi, where it likely conflicts, have you tried against clean 6.18-rcX or next?
